Precision-engineered in Germany, this kit features a 51mm bore size (actual 50.95mm) designed to optimize thermal efficiency and provide superior strength.\n\nThe advanced elliptical design of the piston ensures uniform load distribution as the engine heats up and expands. This critical feature minimizes localized pressure points, significantly reducing the risk of piston collapse and extending engine life. The forged construction provides increased structural integrity compared to cast pistons.\n\n#### Key Features:\n\n \n- Forged construction for superior strength and durability.\n \n- Engineered to improve heat transfer to the cylinder walls for better thermal efficiency.\n \n- Elliptical profile for even thrust load distribution under heat expansion.\n \n- Manufactured to high standards in Germany.\n\n#### Specifications:\n\n \n- Bore Size: 51.00mm (50.95mm actual)\n \n- Display Volume: 79 cm&sup3;\n \n- Stroke: 41.40 mm\n \n- Clearance: 0.05 mm\n \n- Compression Height: 25.00 mm\n \n- Compression Ratio: 2-stroke (compatible with Wossner and OEM specifications)","weightGrams":null,"fitments":[],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-1984-cr80-5100-wossner-8279d150","buyOneNow":null,"basketWithThis":null}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
